SPECIFICATION forming part of Lettrs' IPatent No. 684,227, dated Octobers, 1901-.' Application fi led April 16, 1961. Serial No. 56;147. (Noman.)

T0 at whoiw it an concern.-

Be it known that LJULIO GUIMARAEsa citizen of Argentina, residing inBerlin, in the Kingdom of'Prussia and Empire of Germany, have inventedcertain new and useful Improvementsin Oil-Lamps,of which the followingis a specification.

This invention relates to improvements in oil-lamps; and the object ofthe invention is to provide a lamp of this kind which will give a verystrong and steady light without the use of a chimney or other protectionfor the flame; and the invention consists in the combination,

in a lamp, with an oil-reservoir, of an airsupply tube extendingupwardly through the reservoir,a reservoir-tube within said air-supplytube and communicating with the reservoir, a wick-tube secured to theupper end of said reservoir-tube, a socket secured to the reservoir atthe upper end of the air-supply tube, a plate on said socket extendingoutwardly beyond the same and inwardly to the wick-tube, an inner capsupported on said plate and having its lower edge opposite the socket,and an outer cap supported on said plate over the inner cap, said platebeing provided with perforations within the inner cap and between theinner and outer caps and said socket being provided with perforationscommunicating with the space below the inner portion of said plate.

In the accompanying drawings, Figure 1 is a vertical central sectionthrough a lamp em bodying my invention. Fig. 2 is a top view of the lampshown in Fig. 1, and Fig. 3 is a section on line A B, Fig. 1.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, a, indicates the reservoir of the lamp, whichis provided with a central air-supply tube b, extending upwardly throughthe same. \Vithin the tube 6 is arranged a reservoir-tube c, which isclosed at the bottom and connected with the reservoir byconnecting-walls (Z, as shown in Figs. 1 and 3. The tubes 1) c areperforated between the walls (I, so as to allow the liquid fuel to passfrom the reservoir into the reservoir-tube c. A flat burner-tubefissecured on the upper end of the tube a and contains a flat wick g, whichcan be raised or lowered by turning the spindle 71-. Below the upperedge of the burner is arranged a dished plate 11, which extends inwardlyinto contact with the burner-tubef, and which is supported by adownwardly-extending socket 7c, soldered or otherwise secured thereto,and which fits over the upwardly-projecting edge Z of the reservoir a.On the plate t' rests an inner burnercap p,the lower diameter of whichcorresponds to the diameter of the cylindrical socket is and is arrangedopposite the same, and over said cap is arranged another slotted cap oflarger diameter, which is also supported on the plate t'.

The foot n of the lamp is provided with openings 0,through whichatmospheric air en ters and passes in upward direction through thechannel between the tubes 1) and c. The plate is perforated Within thecap 19 and also between the caps p and r, and the socket is is providedwith openings communicating with the space below the plate t at itsinner portion opposite the cap 10. Through these openings m of the plateand socket air enters and Iningles with the air supplied from belowthrough the foot n, passing thence through.

the plate '5 for supplying air to the flame within the inner cap,whilethe air entering through the outer perforations of the plate t' passesinto the flame between the caps 17 and 1*. To the flame a considerablequantity of oxygen gas is thus supplied through the central airtube andthe perforations, so that without the use of an incandescent mantle or achimney or other protecting means for the flame a very intense andalmost white flame is obtained.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- In an oil-lamp, the combination, with anoilreservoir, of an air-supply tube extending upwardly through the same,a reservoir-tube within the air-supply tube and communicating with thereservoir, the channel between said tubes communicating through the footof the lamp with the outside air, a Wick-tube secured to the upper endof said reservoirtube, a socket secured to the reservoir at the upperend of the air-supply tube, a plate on said socket extending outwardlybeyondthe same and inwardly to the wick-tube, an inner cap supported onsaid plate and having its lower edge opposite said sockets, and an outercap supported on said plate over the inner In testimony that I claiinthe foregoing as cap, said plate being provided with perforamyinventionI have signed my name in pres tions within the inner cap and between theence of two subscribing witnesses.

inner and outer caps, and said socket being JULIO GUIMARJSES. providedwith perforations communicating Vitnesses:
